Claims.

The present invention relates to a diverter nozzle and more particularly to a nozzle for a bath tub, which has a connection for a. shower bath, together with valve means for controlling the iiow of mixed hot and cold water to either the tub or the shower, or vice versa.

An object of the present invention is to pro vide a diverter nozzle for a bath tub, adapted to receive a shower bath connection, wherein water communication or ilow to the tub or shower may be changed as desired and in which flow communication to the shower is automatically cut ofi with the cessation of water supply to the nozzle.

Another object of the present invention is to provide a diverter nozzle construction adapted for a shower bath connection, wherein flow communication to the shower is maintained solely by water ow and which communication to the shower is automatically cut off on cessation of water dow from the supply, requiring manual reestablishment of flow to the shower.

A. further object of the present invention is to provide a novel packless valve construction which is self-sealing against leakage.

A still further object of the present invention is to provide a cylindrical valve member wherein duid enters axially and escapes radially, whereby the huid pressure is utilized to exert endwise thrust on the member to seal it against leakage, without employment of packing material.

The invention has for a further object the provision oi a valve member comprising two concentrically arranged cylinders closed at corresponding ends with fluid entry at one end of the inner cylinder, and each cylinder provided with a radial discharge port, with the ports arranged in radial alignment.

A further object of the present invention is to provide a Adiverter nozzle for a bath tub wherein water ow may be directed into the tub or into a shower and wherein water flow communication to the shower is automatically out off when the water supply to the nozzle is stopped.

An additional object of the present invention is to provide a diverter nozzle, of the class described, wherein water flow to a tub or shower bath may be established at will and wherein valve means are provided of such nature that when flow communication to the tub is open there is drainage escape from the shower to the tub, which arrangement prevents water iiow to the shower, under such conditions, by creation of a vacuum from the flow of water to the tub.

The above other and further objects of the present invention will be apparent from the following description and accompanying drawing.

'I'he accompanying drawing illustrates an embodiment of the present invention and the views thereof are as follows:

Figure 1 is a top plan view of a diverter nozzle constructed in accordance with the principles of the present invention.

Figure 2 is an elevational View, partially in section, along the line II-II of Figure 1, of the nozzle of Figure l.

Figure 3 is a fragmental vertical sectional view through the valve portion of the nozzle, showing the arrangement of the parts when water now is established between the supply and the shower, with iiow to the tub stopped.

Figure 4 is a fragmental horizontal sectional view, partially in plan, showing the position occupied by the valve member when iow communication is established between the supply and the shower and illustrating the formation of a passageway in the nozzle for delivery of water to the valve member axially thereof, for effecting sealing relationship of the valve, to prevent leakage, without packing.

Figure 5 is a View partially in elevation and partially in sections taken on line V--V of Fig. 4, showing an end view of the valve member and the illustrated form of stop means for limiting the oscillation of the valve member in two directions.

The drawing will now be explained.

The diverter nozzle A has, at its wall end a threaded opening I to receive a supply pipe 2 from a hot and cold water mixing valve, not shown. The pipe 2 discharges into a chamber 3, of circuitous form, communicating with an opening 4, in a wall 5, within the nozzle, for entry of water into the valve chamber 6 of the nozzle.

The valve chamber 6 is cylindrical, with its axis transversely of the nozzle A, opened at one end 'l through which' the valve member, indicated as a whole at B, may be installed and removed for repair or replacement. The end I of the valve chamber is normally closed by a threaded cap 8, as may be observed in Fig. 4.

The discharge end 9 of the nozzle A is bent downwardly to direct water owing therefrom toward the bottom of a tub.

Formed as an integral part of the nozzle A is an upstanding neck I0 which deiines a chamber II communicating by means of an oriiice I2 with the valve chamber B, the upper end of the neck I0 is threaded at I3 to receive a coupling nut I4 for securing a shower bath pipe or connection I5 to the nozzle.

Between the valve chamber 6 and the discharge end of the nozzle is an orifice for water flow to the tub when the valve member B establishes communication between the supply pipe 2 and the tub.

The valve member B comprises two concentrically arranged, radially spaced cylindrical parts I6 and I1 which are closed at similar ends as at I8 and I9 respectively. The opposite end of the inner part |1 is open to the valve chamber 6 and comprises a fluid entry port 20 to the inner cylindrical part I1. The fluid entry port 2U is an axial entry port so that incoming Water under pressure from the supply pipe 2 acts against the closed end I9 of the inner cylindrical part I1 of the valve member B.

The inner cylindrical part I1 is provided with a radial exit port 2| while the outer cylindrical part I8 is provided with a radial exit port 22, of greater size than the port 2|. The ports 2| and 22 are arranged in radial alignment.

'I'he outer cylindrical part I6 is provided with an additional port 23 at 90 to the port 22. The outer cylindrical part I 8 is also provided with a bleeder opening 24 with its axis diametrically opposed to the axis of the additional port 23.

The valve member B is actuated by a stem 25 which passes through a centrally disposed aperture 26 in the plug 8. A handle 21 is secured to the outer end of the stem 25, as by a screw 28.

Formed as an integral part of the wall 5 of the nozzle casting is an abutment 29 having shoulders 30 and 3| (Fig. 5).. The end of the valve member B, opposite to the stem 25 is provided with an arcuate projection 32 having its ends terminating in the diameter of the'valve member, which ends constitute projections for bearing against the shoulders 30 and 3| respectively as the valve member B is oscillated to limit the extent of oscillation of the member.

The handle 21 is so disposed on the stem 25 that when the valve member B is 'in position to establish flow communication between the supply pipe 2 and the tub through the discharge end 9 of the nozzle A, the handle lies at an angle of approximately 45 below the horizontal, as may be observed in Fig. 2, and when the valve member B is oscillated in the opposite direction to establish communication between the supply pipe 2 and the shower the handle is at 45 above the horizontal, as may be observed in Fig. 3. The mounting of the handle 21, in the manner stated, is effective to cause gravital movement of the valve member B from shower communication to tub communication, when the supply of water to the supply pipe 2 is stopped, so that the valve member B thus automatically closes flow communication between the supply pipe 2 and the shower pipe I5 when the water supply is stopped.

Figure 2 illustrates the position of the valve member B when it has been rocked in a direction to establish iiow communication to the tub. In this position, the exit ports 2| and 22 are horizontally disposed and in communication with the orifice 35 to the discharge end of the nozzle A. The additional port 23, of the outer cylindrical part I6 of the valve member, is open to the chamber II of the neck I0 so' that whatever water there may be in the shower may drain into the nozzle A thence to the tub.

When the valve member B is in the position of Fig. 2, that is with water flow communication to the tub established, and Water'is flowing, the passage vof the Water through the exit ports 2| and 22 creates sucient suction within the space between the cylindrical parts I6 and I1 to prevent passage of any water upwardly to the shower.

Fig. 3 illustrates the position of the valve member B and flow communication 4between the supply pipe 2 and the shower I 5 is established. It will be observed here that the exit ports 2| and 22 discharge upwardly into the chamber II of the neck I0, thence to the shower I5. The additional port 23 of the outer cylindrical parts I8 is closed by reason of the fact that it is against a portion ofv the wall of the nozzle casing, and the bleeder opening 24 is in communication with the discharge end ofthe nozzle A.

The provision of the bleeder 24 is to relieve water head pressure in the shower, that is in the pipe I5 connected to the neck I0, when closing the water supply to the pipe 2. This pressure relief enables the gravital movement of the valve member B, that is the handle 21, to drop, so that as soon as the water supply stops the valve member B automatically moves from the position shown in Fig. 3 to that shown in Fig. 2, thus cutting ofi` flow communication to the shower. This is an important feature to prevent wetting of any one when opening the water supply to the nozzle A. If the valve were open to the shower, then such person would be accidentally wetted to his or her detriment. With the automatic valve of the present invention, such accident is avoided.

The valve member B has adjacent its stem end a semi-spherical bearing portion 33 which is maintained in contact with a conical surface 34 of the plug 8. As water under pressure enters the axial entry port 20 of the valve member B, the

pressure of the water forces the spherical member 33 against the conical surface 34 thus effectively establishing a seal therebetween to prevent leakage of water through the plug 8 and accomplishes efficient and effective sealing without the utilization of packing material. This sealing effect is present, irrespective of the angular position of the valve member B Whenever water is admitted to the nozzle A from the supply pipe 2.

It will be observed that the diverter nozzle of the present invention is one which may be readily applied to any bath tub where it is desired to use a shower bath or to install a shower bath in such tub. The provision of the novel means of the present invention enables ready diversion of water to the shower from the tube or vice versa. 'I'he gravital action of the valve member assures at all times that flow communication to the shower is cut off whenever the water supply is stopped. This is a safety feature of obvious advantage.

To establish flow communication between the supply pipe 2 and the shower, it is necessary first of all to open the supply pipe 2 to water pressure whereupon the handle 21 is grasped and swung from the position of Fig. 2 to the position of Fig. 3, such swinging then establishing fluid flow communication to the shower. 'I'he pressure of the water passing to the shower, under these conditions, is suiiicient to maintain the valve member B in flow communication to the shower. This is made possible by the axial entry ports and the radial exit ports from the valve member. As soon as the water supply is stopped, the water head pressure in the shower is relieved through the bleeder 24 and the valve member B is then rotated in clockwise direction as viewed in Fig. 3 to the position of Fig. 2, thus shutting oi flow communication to the shower and opening it to the tub. Any water that there may be in the shower drains downwardly through the additional port 23 and to the tub through the discharge end 9 of the nozzle.

The invention has been described herein more or less precisely as to details, yet it is to be understood that the invention is not to be limited thereby, as changes may be made in the arrangement or proportion of parts and equivalents may be substituted Without departing from the spirit and scope of the invention.
